TPS22996H-Q1 Overview
A load switch is a power management IC that sits between a supply rail and its load, using an internal MOSFET to connect or disconnect power under the control of a logic signal. Within the power-management hierarchy (load switch -> power distribution switch -> power management IC -> semiconductor), load switches add controlled slew rates, fault protection, and rail sequencing that a bare MOSFET cannot provide, making them essential building blocks in multi-rail electronic systems.
Key features include the 13 mOhm typical RON, which minimizes voltage drop and conduction loss at the full 4 A per channel load, independently controlled ON1 and ON2 GPIO-compatible inputs that let a microcontroller sequence each rail separately, and controlled turn-on that limits inrush current when charging large downstream capacitance. The device is AEC-Q100 qualified for automotive use and characterized over -40 C to +125 C.
Technically, the TPS22996H-Q1 integrates the power MOSFET, driver, and control logic in one die, reducing BOM count versus discrete solutions. Per TI documentation, the pins are humidity-robust and able to function with a 100 kOhm short from any pin to GND or power, improving reliability in harsh automotive environments.
Typical applications include automotive infotainment and cluster power distribution, ADAS module periphery-rail switching, telecom line-card power sequencing, and industrial PLC I/O rail control, where low RON and dual independent channels save board space.
Design consideration: at 4 A per channel, PCB copper area under the small DYC package determines thermal rise; verify junction temperature with your actual duty cycle and both-channel loading.

Typical Applications
TPS22996H-Q1 is suitable for 6 applications: Automotive Infotainment Power Distribution, ADAS Sensor Module Rail Switching, Telecom Line-Card Power Sequencing, Industrial PLC I/O Rail Control, Solid-State Drive and Peripheral Power Gating, Battery-Powered Portable and Test Equipment.
Automotive Infotainment Power Distribution
The TPS22996H-Q1 fits automotive infotainment power trees because it is AEC-Q100 qualified over -40 C to +125 C and provides two independently controlled 4 A channels in a 2.1 mm x 1.2 mm footprint. Its 13 mOhm typical RON keeps voltage drop to roughly 52 mV at a 4 A display or audio-amplifier rail, preserving headroom on 5 V supplies. The controlled turn-on limits inrush current when enabling large downstream bulk capacitance, and the ON1/ON2 GPIO inputs let the SoC sequence each rail in the required order. Per TI documentation, humidity-robust pins able to function with a 100 kOhm short add field reliability.
Recommended
ADAS Sensor Module Rail Switching
ADAS camera, radar, and lidar modules require sequenced, low-loss power switching, and the TPS22996H-Q1 aligns well: AEC-Q100 qualification, 0.6 V to 5.5 V input range covering both 1.8 V/3.3 V sensor cores and 5 V analog rails, and 13 mOhm typical RON that limits drop at 4 A sensor loads. The dual channels let one device switch both a sensor core rail and its companion analog rail, saving an IC and layout area. Controlled turn-on suppresses inrush when bulk capacitors on long harness-fed rails charge, and independent ON inputs support fault-isolation strategies where one sensor rail is cycled without disturbing others.
Recommended
Telecom Line-Card Power Sequencing
Telecom systems benefit from the TPS22996H-Q1 family, as noted in TI documentation covering both the TPS22996 and TPS22996H-Q1 devices for telecom applications. The 0.6 V to 5.5 V range switches low-voltage DSP and ASIC core rails as well as 5 V I/O rails, and the 4 A per channel capability covers high-current ASIC power-up. Controlled turn-on reduces inrush when charging decoupling banks on dense line cards, while the independent ON1/ON2 inputs enable power-up and power-down sequencing managed by a CPLD or microcontroller. The small 8-DYC package conserves front-panel-constrained board area in high-density line-card designs.
Recommended
Industrial PLC I/O Rail Control
In industrial programmable-logic controllers, the TPS22996H-Q1 switches sensor and actuator supply rails with minimal loss thanks to 13 mOhm typical RON and 4 A per channel capacity. Although the -Q1 grade targets automotive, its -40 C to +125 C characterization and pin humidity robustness (functional with a 100 kOhm short to GND or power per TI documentation) provide margin in industrial cabinets subject to condensation and vibration. The GPIO-compatible control inputs interface directly to 3.3 V or 5 V PLC logic without level shifting, and the two independent channels allow selective power cycling of I/O groups during fault recovery, improving system availability and diagnostics.
Recommended
Solid-State Drive and Peripheral Power Gating
Storage and peripheral systems use load switches to gate idle device rails for energy savings, and the TPS22996H-Q1 is well matched: 13 mOhm typical RON means only about 52 mV of drop at 4 A, critical for low-voltage 1.2 V to 1.8 V rails where headroom is scarce. The 0.6 V minimum input supports emerging sub-1 V core domains. Controlled turn-on manages inrush into large bulk capacitors on hot-pluggable drive bays, and dual independent channels let one device gate both a controller core rail and an NAND flash rail with separate ON control from the host management controller, simplifying power-state machine implementation.
Recommended
Battery-Powered Portable and Test Equipment
Portable instruments and battery-powered equipment gain from the TPS22996H-Q1's low 0.6 V minimum input and 5.5 V maximum, which covers single-cell Li-ion stacks (down to deep discharge) and USB 5 V rails. The 13 mOhm typical RON minimizes conduction loss that would otherwise drain batteries in always-on paths, and controlled turn-on prevents voltage sag at the battery when switching 4 A loads. Two independent channels enable selective shutdown of high-current subsystems for aggressive power-state management. The compact 2.1 mm x 1.2 mm DYC package fits the dense layouts typical of handheld test and measurement products.

Key Differentiators
- AEC-Q100 automotive qualification (vs TPS22996)
- Dual 4 A channels in 2.1 mm x 1.2 mm (vs TPS22996N)
- Humidity-robust pins (vs TPS22996)
Design Notes
Estimated: at 4 A per channel with 13 mOhm typical RON, each channel dissipates about 208 mW; dual-channel full load is roughly 416 mW in a 2.1 mm x 1.2 mm 8-DYC package. Because the DYC land pattern is small, theta-JA is dominated by board copper: maximize the GND pour under the part, add thermal vias to inner planes, and confirm junction temperature against the -40 C to +125 C operating range using your actual duty cycle. Avoid continuous dual-channel 4 A loading without verified copper area.
Route VIN, VOUT1, and VOUT2 with wide traces or pours sized for 4 A continuous current to limit IR drop and heating - at 4 A even 10 mOhm of trace adds 40 mV drop and 160 mW loss per path. Place the switch close to the load to minimize radiating loop area during switching events, and keep the ON1/ON2 control traces away from high-di/dt power paths. Follow the TI datasheet recommended land pattern for the 8-DYC (SOT-583) footprint.
Controlled turn-on limits inrush, but verify the slew time against downstream bulk capacitance so startup stays within the SOA of the internal MOSFETs - very large capacitor banks on the output still produce long inrush events. Do not exceed the 5.5 V absolute maximum input, including automotive load-dump clamped transients on pre-regulated rails. When substituting the commercial TPS22996 into a -Q1 socket, confirm the target program permits non-AEC-Q100 parts; the reverse is safe but the forward may violate qualification.
